ROD-PACKING.

SPECIFICATION forming part of Letters Patent No. 266,031, dated October 17, 1882.

Application filed March 11, 1882.

To all whom it may concern:

Be it known that I, \VILLIAM HAAS, of the city, county, and State of New York, have invented certain new and useful Improvements in Rod-Packing, of which the following is a specification.

The object of this invention is to furnish an improved packing for steam-valves and stufl'- ing-boxes; and the irtvention consists of a packing made of small shot of a suitable antil'riction metal, said shot filling the space around the stem of the valve or piston-rod of the stuffing-box, and being retained at one or both sides by an asbestus or other packingring.

In the accompanying drawings, Figures 1 and. 2 represent vertical central sections of a valve and of a stuffing-box with my improved packing".

Similar letters of reference indicate corresponding parts.

A represents the stem of a steam-valve or the piston-rod of a stuffing-box; B, the exterior casing of the valve or stuffing-box and G the packing, which is composed otfine shotot'any suitable anti-friction metal, which is made to till the entire annular space around the valvestem or piston-rod and the casing. In place of the shot, other small irregular pieces of metal may he used for fillingthe space around 0 (N0 model.)

the valve-stem 0r rod; butI preferround pieces, such as fine shot. A packing-ring, D, of asbestus or other suitable material is arranged at one or both sides of the packing 0, so as to properly confine the same. The shot or other small pieces of metal serves as a steam-tight packing, owing to the fact that the steam condenses in the small intermediate spaces formed between the shot or other pieces of metal. This Waterof condensation forms also a kind of lubricant for the valve-stem or piston-rod, whereby the motion is facilitated and the durability of the packing increased.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination, with asteam-"alve or stuffing-box and a valve-stem or piston rod,of a packing of fine shot placed in a cavity of the valveorstufting-boxaroundthevalve-spindleor piston-rod, and retained by a pack ing-ring'and tightening-sleeve, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence oftwo subscribing witnesses.

WILLIAM HAAS.
